Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening handrail applied to a doorway portion of a house, a hospital or the like.

[0002]

2. Description of the Related Art Conventionally, for example, as disclosed in Japanese Patent Laid-Open No. 61-95158, an upper base end mainly composed of a handrail is connected to a bracket via a shaft portion, and a locking projection formed on a lower base end is provided. Disclosed is a movable type handrail characterized in that the handrail main body is securely fixed at a use position by meshing with an engagement recess to prevent an unexpected accident.

However, the movable handrail in this technology is
A movable handrail main body connected to a bracket mounted on a wall is rotatable within a range of 90 ° in a horizontal rotation plane of the handrail main body, but since the handrail main body has a small turning radius, It wasn't mobile enough to rely on and walk.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above facts, and an object of the present invention is to inconvenience that a handrail handed down by a physically handicapped person or the like is interrupted by a door. To provide a handrail that can safely pass in front of the door.

[0005] In addition, when an elderly person or a person with a physical disability enters or leaves a house or other public facilities for a walk, shopping, a visit, an outpatient clinic, etc.,
It is to provide handrails for openings that can be safely walked.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a bar-shaped handrail having a rotary hinge provided as a fulcrum on a wall near one side of an indoor doorway is used as a fulcrum. A pedestal provided on a wall portion near the other side of the entrance door that is rotatable in a plane parallel to the wall surface from a vertical state to a horizontal state and that receives the free end of the rod-shaped handrail, and the handrail use The gist of the present invention is an opening handrail that is composed of a latch device that sometimes prevents the door from opening and closing and a safety device that prevents the handrail from rotating while the door is opening and closing.

In the rotating device according to the present invention, one end of the bar-shaped handrail is joined to the rotary hinge to serve as a fulcrum of rotation, and the bar-shaped handrail is rotatable by 90 ° in a plane parallel to the wall surface. The free end of the handrail is received by a handrail pedestal provided near the other side of the doorway to form an opening handrail.

At this time, the rotating device rotates the rod-shaped handrail electrically for the person himself or manually for the helper, and receives the free end of the handrail on the pedestal.

As a safety device of the present invention, a latch device for prohibiting opening and closing of the door when the handrail is used is provided.

Further, as the safety device of the present invention, a safety device for preventing the handrail from rotating during opening and closing of the door is provided.

The procedure for safely opening and closing the door is as follows. Press the switch to rotate the rod-shaped upright handrail. However, the safety device is activated and the door latch device is locked and does not open. . Rotate the handrail 90 ° to level it and place it on the pedestal at the other end of the door. After walking along the handrail, press the switch on the opposite side to rotate the handrail and return it to its original position. By the above procedure, the safety device is disengaged, the door latch device is opened, and the door can be opened.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a handrail for opening,
2, 2 ′ are handrails attached to the wall surface, 3 is a rotating device, 4 is a cradle for receiving the opening handrail 1,
Also, 5 and 5'are switches arranged on both sides of the door,
6 is a door, 7 is an electric lock, 8 and 8'are bevel gears, and 9 is a motor.

The opening handrail 1 is rotatably attached to a side wall portion of one end of the door 6 via a rotating device (rotating hinge) 3. In this case, the rotating device is electrically operated for the person, and manually for an assistant to rotate the rotating device to mount the pedestal 4 mounted on the other end side wall portion of the door 6.
Then, the free end of the handrail 1 for opening is set.

When the handrail 1 is tilted from the vertical state to the horizontal state, the handrail 1 turns on the electric lock 7 and prohibits the opening and closing of the door 6. Further, when the handrail 1 is erected from the horizontal state to the vertical state, the electric lock is turned off and the door 6 can be opened and closed.

At this time, the switches 5 and 5'mounted on the left and right wall surfaces of the door are the motor 9 and the bevel gears 8 and 8 '.
The handrail 1 is set from the horizontal state to the vertical state or from the vertical state to the horizontal state by the rotation mechanism of.

That is, when the handrail 1 is in the horizontal state and the ON (UP) button of the switch 5 or 5'is pressed, the handrail 1
Turns 1/4 turn into a vertical state, and opening and closing of the door is permitted. In addition, when the handrail 1 is in the vertical state, the switch 5
Or if you press the 5'OFF (DOWN) button, the handrail 1
Turns 1/4 turn to a horizontal position and prohibits opening and closing of the door. Then, the free end of the handrail 1 is set on the cradle 4. At the same time, the electric lock 7 is turned on to lock the door 6.

This avoids the risk of a person in the room suddenly opening the door, thereby causing an obstacle such as a collision of the door with a person who happens to pass through the corridor.

EFFECTS OF THE INVENTION Elderly people, especially late-stage elderly people (75 years old or older)
A healthy person or an elderly person who has some disabilities (for example, slight paralysis, rheumatism, etc.) is worried when walking indoors or outdoors and often walks. Therefore, a walking stick or a handrail is often used when walking. By using the opening handrail of the present invention, a person who is uneasy about his / her health can walk along the handrail in a house and live a safe life. In addition, even for elderly people who often go out late, by using the opening handrail of the present invention, they can actively participate in visits or meetings without anxiety, and enjoy a safe and comfortable life.
